Every beginner needs to learn the names of the keys and how to read notes. Learn quickly with our large print, easy-to-see KeyStrips. Like a musical yardstick, they fit in the "groove" at the back of your black and white keys. They are easier than keyboard stickers and cover the entire range of keyboard notes. KeyStrips are printed on heavy card stock and are over 32" long! KeyStrips are made for 49, 61and 73 note CASIOs with full-sized keys.
